Abstract
The main objective of this study was to evaluate the effectiveness of the Program Targeting Children with 'Chest Wheezing' carried in the city of Embu, São Paulo. The study analyzed a total of 434 children aged zero to 14 years, admitted to the program from May 1988 to July 1993. Over 90% had never been treated for this medical problem in outpatient clinics. Only 6.2% had to be referred to other health care services during follow-up in this program. The program successfully performed clinical diagnosis of asthma in children over 2 years of age. The moderate and severe cases followed up for over a year showed the best clinical evolution, with the positive factor being better compliance with medication. The number of exacerbations decreased among the severe patients after a year of regular follow-up, although patients used bronchodilators during the 12 months of our analysis. Of the children enrolled, 53.2% gave up treatment principally in the first six months, most of them from the moderate group. We concluded that children with steadier compliance with the program benefited in spite of both the simplicity and the lack of some currently existing medications.

Abstract
BACKGROUND African-American children use the emergency department (ED) for asthma care more than their Caucasian counterparts. OBJECTIVE We sought to compare ED utilization for asthma care by race, adjusting for prescriptions filled for antiinflammatory medications, type of index visit (specialist vs nonspecialist), and demographic variables. METHODS An index asthma visit was identified for a cohort of managed care enrollees aged 4 to 11 years. Information on asthma encounters and drug claims data was evaluated during a prospective observation period of 12 months. RESULTS African-American race was associated with one or more ED visits during the observation period (relative risk [RR] = 1.8, 95% CI = 1.3 to 2.5, p < 0.01). After adjusting for index visit type, prescriptions filled, and selected demographic variables, African-American race remained associated with post-index ED utilization (adjusted RR = 1.6, 95% CI = 1.0 to 2.4, p = 0.05). Additional findings included an inverse relationship between African-American race and antiinflammatory medications among children with nonspecialist index visits (RR = 0.5, 95% CI = 0.3 to 0.9, p = 0.02) and a positive relationship between African-American race and hospitalization after an ED visit for asthma care (RR = 10.2, 95% CI = 1.4 to 74.8, p < 0.01). CONCLUSION African-American children were more likely to use ED asthma care even after adjusting for the type of index visit, prescriptions filled for antiinflammatory medications, and selected demographic variables. Racial differences in ED utilization for asthma care could be caused by a higher prevalence of uncontrolled or undertreated disease among African-American children not receiving specialty care.

Abstract
The objective of this study was to describe perceptions of asthma care, morbidity, and health service utilization by parents of children with asthma presenting to an inner-city emergency department (ED). A cross-sectional survey was conducted in an urban pediatric ED, with a convenience sample of 466 parents of children receiving asthma treatment during a consecutive 6-week period in late fall 1995. Parents completed a 30-item survey including sociodemographic data, source of primary medical care and asthma care for their child, selected measures of access to care, and medications used by their child in the week prior to the ED visit. Perceived quality of asthma care was measured by six items (summary score = 0-6) reported to have been performed by the child's asthma doctor: discussion of home peak flow monitoring, child-specific triggers, dogs/cats, smoke, postexacerbation calling instructions, and provision of a written asthma management plan. Functional morbidity was measured by nights of poor sleep, days of cough, and school days missed due to asthma in the previous month. Among 325 patients with previously diagnosed asthma, 308 (97%) were reported to have a source of primary medical care. Of these, 126 respondents identified their primary care provider as the child's usual source of asthma care, while 158 identified the ED as the usual source. The groups did not differ by insurance status, ethnicity, or mean age of the child. Thirty-nine percent of children with the same provider for primary and asthma care compared with 15% of children reported to receive their asthma care predominantly in the ED had used inhaled steroids or cromolyn in the week prior to the ED visit (p < .0001). Children with the same provider for primary and asthma care had a higher mean quality score than children receiving asthma care in the ED (3.7 vs. 2.8, p < 0.0001), but there was no relationship between source of asthma care and functional morbidity. The ED remains the usual source of asthma care for many inner-city children. Among parents surveyed in the ED, there was a significant relationship between source of usual asthma care and quality of care, but a relationship between usual source of asthma care and functional morbidity could not be identified.

Abstract
OBJECTIVE The purpose of the study was to examine medication use reported by families participating in an urban school-based community intervention program and to relate this use to other social and medical variables. DESIGN The design of the study was a cross-sectional questionnaire survey. SETTING Patients and their families recruited from elementary schools in a community setting were interviewed between December 1991 and January 1992. PARTICIPANTS A total of 508 children with asthma were identified by school health records and teacher surveys. Their families confirmed the diagnosis and agreed to enter the study. Questionnaires were completed by 392 families. INTERVENTION The 392 families participated in a controlled trial of asthma education after providing the data that are the basis of this report. RESULTS More than half of the children took two or more medications for asthma. Thirty-one percent took theophylline alone or in combination with an adrenergic agent; 11% took some form of daily antiinflammatory medication, either cromolyn (8%) or inhaled steroids (3%). The pattern of medication use related to measures of severity and to regular visits to physicians or nurses. In general, however, children were undermedicated. A total of 78 children (20%) reported no medication or over-the-counter medication use, although 37% reported asthma severe enough to be associated with >/=20 days of school missed per month, and 37% had had an emergency room visit for asthma in the past 6 months. More than half of children >/=9 years old supervised their own medication. CONCLUSIONS We concluded that undermedication is common in poor children with asthma living in urban areas. Antiinflammatory medications are used less commonly than in the general population, and theophylline is used more often. School children may be likely to supervise their own medication.

Abstract
OBJECTIVE Based on family history, infants may be classified as "high risk" or "low risk" for the development of allergy or asthma. Failure to breast-feed and early exposure to cigarette smoke or aeroallergens increase the risk of developing asthma or allergy. Since we suspect that physicians seldom educate mothers on reducing environmental exposures in the postnatal period, we sought to determine the level of maternal knowledge as well as actual avoidance behaviors with respect to these risk factors in high risk and low risk families. DESIGN Questionnaire administered by a research assistant. SETTING Obstetrics unit of two tertiary care general hospitals. PATIENTS A sample of 194 postpartum women with uncomplicated pregnancies, interviewed after 24-hours postpartum. MAIN OUTCOME MEASURES (1) Parental history of asthma, allergy or eczema; (2) potential for infant exposure to environmental risk factors for asthma and allergy, as indicated by history of avoidance practices in the home; (3) parental knowledge of risk factors for asthma or allergy; and (4) physician advise on avoidance. RESULTS Of 194 women interviewed, a history of doctor-diagnosed asthma, allergy/allergic rhinitis or eczema in either parent was reported by 122 (high risk group). The remaining 72 patients had no history of atopy (low risk group). Of those in the high risk group, 10% of mothers smoked during pregnancy, and about 25% were exposed to second hand smoke on a daily basis. Most of the mothers in the high risk group planned to breast feed (89%). A large number of patients in the high risk group reported potential risk factors for allergy/asthma in their home environments. These included animals in the household (36%), dusty environments (10%) carpeting (47%), cigarette smoke (18%), and others. Despite these risks, only 13% of patients reported being educated by their physicians on improving their home environment. Exposures to environmental risk factors were not different between low and high risk groups. Similarly, knowledge of environmental risk factors and avoidance behaviors were not significantly different between low and high risk groups. CONCLUSIONS Many mothers whose infants are at high risk of developing asthma or allergies are not aware of and do not practice avoidance of risk factors. Physicians involved in prenatal care of women with a family history of atopy and asthma should offer advice on reducing exposure to potential risk factors and how to modify their environment in ways that can potentially decrease the risk of asthma or allergy prevalence and severity.

Abstract
BACKGROUND In asthma, socio-economic and health care factors may operate by a number of mechanisms to influence asthma morbidity and mortality. AIM To determine the quality of medical care including the patient perception of the doctor-patient relationship, and the level of socio-economic disadvantage in patients admitted to hospital with acute severe asthma. METHODS One hundred and thirty-eight patients (15-50 years) admitted to hospital (general ward or intensive care unit) with acute asthma were prospectively assessed using a number of previously validated instruments. RESULTS The initial subjects had severe asthma on admission (pH = 7.3 +/- 0.2, PaCO2 = 7.1 +/- 5.0 kPa, n = 90) but short hospital stay (3.7 +/- 2.6 days). Although having high morbidity (40% had hospital admission in the last year and 60% had moderate/severe interference with sleep and/or ability to exercise), they had indicators of good ongoing medical care (96% had a regular GP, 80% were prescribed inhaled steroids, 84% had a peak flow meter, GP measured peak flow routinely in 80%, 52% had a written crisis plan and 44% had a supply of steroids at home). However, they were severely economically disadvantaged (53% had experienced financial difficulties in the last year, and for 35% of households the only income was a social security benefit). In the last year 39% had delayed or put off GP visit because of cost. Management of the index attack was compromised by concern about medical costs in 16% and time off work in 20%. CONCLUSION Patients admitted to hospital with acute asthma have evidence of good quality on-going medical care, but are economically disadvantaged. If issues such as financial barriers to health care are not acknowledged and addressed, the health care services for asthmatics will not be effectively utilised and the current reductions in morbidity and mortality may not be maintained.

Abstract
BACKGROUND Acute asthma attacks are frequent causes of attendance at hospital Emergency Departments (EDs) and a subgroup of these patients repeatedly present for such treatment. AIMS This study sought to characterise patients who were repeat attenders at EDs, to assist the targetting of appropriate future interventions aimed at reducing avoidable presentation. METHODS A cross-sectional survey was undertaken of patients presenting with an asthma attack to the EDs of six teaching hospitals in Adelaide, South Australia between 14 May and 30 June 1994. Patients were interviewed within six weeks of their attendance about aspects of their asthma history, severity, medications, self-management, attitudes and environment. Repeat attenders, defined as two or more visits over the course of the preceding year, were compared with those who reportedly attended on one occasion only, using logistic regression analyses. RESULTS Sixty-two per cent of 272 patients aged under 15 years and 40% of 165 patients aged 15 years or more reported having attended two or more times over the course of the preceding year. Among adults, the variables independently associated with repeat attendance principally related to asthma severity. Among children, repeat attendance was associated with parental attitudinal variables relating to appraisal of their child's asthma severity, management of asthma attacks and parental worry. CONCLUSIONS The factors underlying repeated presentations at EDs differ between adults and children and interventions to minimise avoidable presentation will require different emphasis for these patient subgroups.

Abstract
BACKGROUND Demographic and socioeconomic factors have an impact upon the morbidity and mortality rates of asthma in inner-city pediatric populations. Many pediatric patients with asthma use the emergency room as their primary care physician, while a smaller number of children with asthma use the allergy-immunology clinic. OBJECTIVE We examined the demographic and socioeconomic characteristics of asthmatic patients using the emergency room as their primary care physician and of those attending the allergy-immunology clinic in the same inner-city hospital. We compared the morbidity and cost of care of asthmatic patients who received their medical care in the emergency room to that of those who received their care in the allergy-immunology clinic. METHODS Fifty consecutive emergency room patients and 25 clinic patients were studied using an identical questionnaire. RESULTS There was no difference between the two groups in the total number of individuals per household, children per family, monthly income, type or size of dwelling, financial problems purchasing medications, health insurance type, distance to the medical center, or education of the caretaker. Severity of asthma was not different in the two groups before the start of the study. The only significant demographic difference was in age: 10.6 years for the clinic group and 7.8 years for the emergency room group (P < .002). Clinically, in the year preceding the interview, the clinic group had significantly less nocturnal cough (P < .025), sleep interruption (P < .001), weekly asthma (P < .05), and emergency room visits (P < .09). The allergy clinic group had an approximate average savings of $137 per patient per year. Hospital admissions and emergency room costs were increased by a small group of three allergy clinic patients, decreasing the difference in the cost of care between the two groups. CONCLUSION The data showed that patients who attended the emergency room and those who attended the allergy-immunology clinic were not demographically or socioeconomically different. The decreased morbidity of asthma and cost of care for the allergy clinic patients, as opposed to the emergency room patients, are likely due to the care given in the allergy-immunology clinic.

Abstract
BACKGROUND Cockroach allergen, Bla g 1, is an important indoor allergen. Although household exposure has been documented, little is known about the potential for exposure outside the home. OBJECTIVE We investigated the settled dust concentration of Bla g 1 in 147 samples collected from classrooms, kitchens, cafeterias, and other sites in four primary schools in the city of Baltimore. METHODS School authorities were questioned about characteristics of schools, teachers, and students, as well as cockroach control and cleaning procedures. Settled dust samples were collected with a hand-held vacuum cleaner from the floors of all classrooms, food-related areas, and other sites of the schools over a 3-week period. A sample collection in each school took 1 to 2 days. Dust samples from each room were pooled and analyzed as a single sample for Bla g 1 by using a two-site monoclonal ELISA. RESULTS One hundred two (69%) of the 147 samples had detectable Bla g 1 and were within the range reported by other investigators in inner city homes. There was no difference between the median levels of Bla g 1 in three schools: school 1 (5.2 U/gm), school 2 (3.0 U/gm), and school 4 (2.7 U/gm); but school 3 had a significantly lower level (< 0.8 U/gm, p < 0.001). The median level from the food-related areas was significantly higher than the median classroom level (p = 0.048). School 3 had fewer students on subsidized lunch, fewer African-American students, and fewer students per teacher. Bla g 1 levels were compared in the different schools while controlling for potential confounding variables by a stepwise multiple regression analysis with a logit model for ordinal responses. On the basis of this analysis, Bla g 1 levels in schools 1, 2, and 4 differed significantly from levels in school 3 (p < 0.001 in each case). Food-related areas had significantly higher levels than classrooms (p = 0.048). Floor level, the presence of a sink, and the presence of carpeting did not have significant effects. CONCLUSIONS We conclude that Bla g 1 is detectable at potentially significant concentrations in some inner city schools. Furthermore, the level of exposure is different between different schools and between sites within individual schools.

Abstract
This study documented the prevalence of exercise-induced asthma (bronchospasm) in rural elementary schools and described the use of a free-running asthma screening test (exercise-challenge) and peak expiratory flow rate measurements for screening in a school setting. Of 437 children screened, 25 (5.72%) had a > or = 15% decrease in post-exercise peak expiratory flow rate which is indicative of exercise-induced asthma. Absenteeism and poverty were associated with findings of exercise-induced asthma. Early detection of exercise-induced asthma in school-age children through screening would facilitate early treatment, enhance exercise-related activities, and decreases school absences.

Abstract
BACKGROUND Dependence on crisis-oriented care rather than continuous ambulatory care for asthma is thought to contribute to asthma morbidity and mortality. We contrasted the characteristics of patients who depend on emergency department (ED) care for the management of their asthma exacerbations to the characteristics of patients employing self-management plans in an ambulatory setting. METHODS In prospective fashion, we used a structured interview and charted information to survey two cohorts of patients suffering from an acute exacerbation of asthma; those seen in a hospital ED (n = 80) and those seen in an ambulatory asthma care facility (Asthma Center [AC]) (n = 40) at the same hospital. We looked for differences in socioeconomic characteristics, asthma severity, asthma knowledge, and asthma self-management skills between groups. RESULTS There were no significant differences in mean age (SD) (ED vs AC: 36.65 [13.8] vs 40 [13.8] years) or female to male ratio (ED vs AC: 2/1 vs 2.5/1) between the two groups. There were no major differences in ethnic origin, educational status, marital status, smoking history, employment status, number of children in the household, possession of an extended health insurance plan, sick leave benefits, and child care availability between the two groups. Patients seeking ED care were more likely to have resided in the city for < 5 years (34% vs 8%; p < 0.05), and more likely to be living alone (35% vs 15%; p < 0.05). Significantly more patients from the ED group had a below average gross annual income (55% vs 3%; p < 0.05). There were several significant differences between groups in their knowledge of asthma and its therapy. Most striking, 79% of AC patients reported having a predetermined crisis plan vs just 23% of ED patients (p < 0.001). Although measurements of airflow (percent predicted FEV1) were significantly lower in the ED group than the AC group (mean, 50% vs 78.4%; p < 0.001), other indexes reflecting the degree of asthma severity over the long term such as past use of oral steroids, history of hospitalization, or ICU admission for asthma and the mean total days of disability within the preceding year were not significantly different between the two groups. Most of the ED patients had more than one previous visit to the ED for asthma exacerbation within the preceding year while most exacerbations of AC patients had been treated in the ambulatory care setting. Only 17% of ED patients initiated or increased inhaled or oral steroids before seeking medical care vs 89% of AC patients (p < 0.001). CONCLUSION We conclude that a subgroup of asthmatics depends primarily on crisis-oriented care for the management of asthma. These patients are more likely to have lower income, to live alone, and to have resided at their current address for less time than patients seeking less urgent ambulatory care. Moreover, such patients are less knowledgeable about asthma and its management and are less likely to have a predetermined crisis plan.

Abstract
OBJECTIVE Recent studies have shown that lack of continuing primary care for asthma is associated with increased levels of morbidity in low-income minority children. Although effective preventive therapy is available, many African-American and Latino children receive episodic treatment for asthma that does not follow current guidelines for care. To see if access, continuity, and quality of care could be improved in pediatric clinics serving low-income children in New York City, we trained staff in New York City Bureau of Child Health clinics to provide continuing, preventive care for asthma. METHODS We evaluated the impact of the intervention over a 2-year period in a controlled study of 22 clinics. Training for intervention clinic staff was based on National Asthma Education and Prevention Program guidelines for the diagnosis and management of asthma, and included screening to identify new cases and health education to improve family management. The intervention included strong administrative support by the Bureau of Child Health to promote staff behavior change. We hypothesized that after the intervention, clinics that received the intervention would, compared with control clinics, have increased numbers of children with asthma receiving continuing care in the clinics and increased staff use of new pharmacologic and educational treatment methods. RESULTS In both the first and second follow-up years, the intervention clinics had greater positive changes than control clinics on measures of access, continuity, and quality of care. For second year follow-up data these include: for access, greater rate of new asthma patients (40/1000 vs 16/1000; P < .01); for continuity, greater percentage of asthma patients returning for treatment 2 years in a row (42% vs 12%; P < .001) and greater annual frequency of scheduled visits for asthma per patient (1.85 vs .88; P < .001); and for quality, greater percentage of patients receiving inhaled beta agonists (52% vs 15%; P < .001) and inhaled antiinflammatory drugs (25% vs 2%; P < .001), and greater percentages of parents who reported receiving patient education on 12 topics from Bureau of Child Health physicians (71% vs 58%; P < .01) and nurses (61% vs 44%; P < .05). CONCLUSION We conclude that the intervention substantially increased the Bureau of Child Health staff's ability to identify children with asthma, involve them in continuing care, and provide them with state-of-the-art care for asthma.

Abstract
The purpose of this study was to describe patterns of health care use by inner-city patients with asthma and to identify patients at risk for hospitalization. We performed a retrospective cohort study of 1788 patients with asthma aged 5 to 34 years from a large hospital-based multi-specialty practice in inner-city Indianapolis from 1985 to 1992. Compared with 633 white patients, 1155 African-American patients had fewer outpatient encounters including primary care visits, urgent visits to the emergency department and urgent care centers, and prescription refills. Emergency department use was greater for African-American males compared with white males. With patients 30 years of age as the referent, survival analysis revealed three to sixfold greater relative risk of hospitalization for asthma for younger patient age groups, and greatest risk among young African-American males. Adolescent patients had the highest cumulative percentage hospitalization and the longest lengths of stay. We conclude that inadequate routine primary care among African-American patients may increase their risk of asthma exacerbation requiring hospitalization. Age, gender, and race are all important predictors of hospitalization for asthma. Further studies are needed to explore the relation between sources of care and asthma exacerbation.

Abstract
Objective: To use routine data from a comprehensive
electronic medical record system to predict death among patients with reactive
airways disease. Design: Retrospective cohort study conducted in an academic primary
care internal medicine practice. Subjects were 1,536 adults with reactive
airways disease: 542 with asthma and 994 with chronic obstructive pulmonary
disease (COPD). Measurements: The dependent variable was death from any cause within
3 years following patients' first primary care appointment in 1992.
Multivariable logistic regression was used to identify independent predictors
of 3-year mortality, with half of the patients used to derive the predictive
model and the other half used to assess its predictability. Results: Of the 1,536 study patients, 191 (12%) died in the 3-year
follow-up period. From information available on or before patients' first
primary care visit in 1992, multivariable predictors of 3-year mortality were
coincidental heart failure, male sex, presence of COPD, lower weight, low
serum albumin concentration level, and a prior arterial PO2 of less
than 60 mmHg; use of an inhaled corticosteroid was protective. The c-statistic
(ROC curve area) in the validation cohort was 0.76, indicating good
discrimination, and goodness of fit was excellent by Hosmer-Lemeshow
chi-square (P > 0.5). Only 24% of the patients in the validation cohort
were designated at high risk (estimated ≥15% 3-year mortality), but this
group contained more than half of the deaths within 3 years for the entire
cohort. Conclusions: Data generated during routine care and stored in a
comprehensive electronic medical record can accurately predict mortality among
patients with reactive airways disease. Such technology can be used by
practices to control for severity of illness when assessing clinical practice
and to identify high-risk patients for interventions to improve prognosis.

Abstract
BACKGROUND Studies have shown a higher prevalence of asthma among boys compared with girls and in blacks compared with whites, but it has been difficult to separate socioeconomic from racial effects because the blacks in the studied populations were more likely to have low socioeconomic status. OBJECTIVE To compare the prevalence of asthma in a socioeconomically homogeneous, middle class, multiethnic population of schoolchildren. METHODS Based on a telephone survey of all families of third-graders in Southfield, Michigan, we ascertained the prevalence of physician-diagnosed asthma and probable undiagnosed asthma. One reason Southfield was chosen for study was because the city comprises an integrated middle class population with only 4% blacks and 7% whites having incomes below federal poverty limits. RESULTS The lifetime prevalence of asthma was 9.5% (12% for blacks and 6% for whites) and higher in boys (14%) than girls (5%), a pattern that was reflected in period prevalence estimates. The lifetime prevalence of probable undiagnosed asthma was greater in blacks (16.6%) than whites (10.8%), with little sex difference. Adjusting for sex and maternal education, the prevalence of physician-diagnosed asthma and probable asthma were associated independently with black ethnicity. CONCLUSIONS Our study is unique in the similarity of the black and white families' socioeconomic status and residence in the same middle class community. Since access to medical care and macro-environmental conditions were similar across this study population, our results are consistent with the hypothesis that differences in biologic factors between blacks and whites and boys and girls play a role in asthma risk.

Abstract
OBJECTIVE The extent to which urban children endure the symptoms and consequences of asthma without a physician diagnosis has not been well studied. Our objective was to obtain an estimate of the prevalence of possible undiagnosed asthma in a population of urban schoolchildren. DESIGN AND METHODS A population-based cross-sectional study was conducted in urban schoolchildren, grades 3 to 5. Undiagnosed asthma was defined as caretaker report of symptoms and/or bronchial hyperresponsiveness, defined as a 15% or greater drop in baseline forced expiratory volume in 1 second, after exercise challenge. RESULTS A total of 230 children (61% of those eligible) participated in the study. Forty children (17.4%; 95% Confidence interval (CI) = 12.5% to 22.3%) had reports of a physician diagnosis of asthma. Of these, 33 (14.3%; (95% CI = 9.8% to 18.9%) reported wheezing in the past 12 months. Among the remaining 189 eligible children, 11 (5.8%; 95% CI = 2.5% to 9.2%) met study criteria for undiagnosed asthma based on bronchial hyperresponsiveness (BHR). Another 16 (8.5%; 95% CI = 4.5% to 12.4%) met study criteria for undiagnosed asthma through modified American Thoracic Society symptom criteria. Overall, 27 children (27/189; 14.3%) fulfilled criteria for undiagnosed asthma. Children identified as having undiagnosed asthma were compared with children who had no BHR and no symptoms and who did not report a physician diagnosis of asthma (children without asthma). Children with BHR were more likely to have a report of allergies and eczema than children without asthma, odds ratios (OR) = 8.5 (95% CI = 2.4 to 30.7) and 6.4 (95% CI = 1.1 to 38.1), respectively. Children meeting symptom criteria were more likely to have a report of allergies, OR = 6.2 (95% CI = 2.0 to 19.1), and bronchitis, OR = 6.7 (95% CI = 2.0 to 22.4), and were also more likely to report sleep disruption, OR = 7.1 (95% CI = 2.3 to 21.8) and missed physical education classes, OR = 15.0 (95% CI = 4.8 to 46.7), compared with children without asthma. CONCLUSIONS We estimated a prevalence of 14.3% for possible undiagnosed asthma among urban schoolchildren, grades 3 to 5, through caretaker report of symptoms or BHR postexercise challenge. Children with undiagnosed asthma reported more atopic disease than children without asthma. In addition, children meeting symptom criteria for asthma reported more bronchitis, sleep disruption, and missed physical education classes than did those without asthma. These results suggest that rates of undiagnosed asthma may be high in this predominantly black school-age population.

Abstract
Asthma is one of the most common chronic illnesses in childhood. Increases in hospitalization rates have occurred in several countries. The cumulative risk of asthma requiring medical attention was 11.7% for males and 7.0% for females aged 0-4 in Manitoba, Canada, for the cohort of children born in 1984/1985. The cumulative risk of hospitalization for males was nearly twice that of females (2.1% vs. 1.1%). Disease onset was most likely at age 1 year. The risk of rehospitalization or return physician visit for asthma increased significantly with the number of prior hospitalizations and physician visits, respectively, which may reflect both the persistence of asthma and the difficulty of developing an effective disease management strategy.

Abstract
Asthma is a serious global health problem affecting nearly 100 million people worldwide. Its rising prevalence and associated morbidity and mortality are of increasing concern. Traditionally, symptomatic control of bronchoconstriction with beta 2 agonists and theophylline has been the mainstay of therapy. However, during recent years, inflammation has been recognised as the predominant cause of reversible airway obstruction and airway hyperreactivity. As a result, the emphasis in treatment has shifted to the early use of inhaled corticosteroids to control airway inflammation. beta 2 agonists are best used on an as-needed basis for the relief of acute bronchoconstriction and for the prevention of exercise-induced asthma. Sustained release theophylline or an inhaled long-acting beta 2 agonist may effectively control nocturnal symptoms. Preliminary studies involving agents active in the 5-lipoxygenase pathway as preventive therapy are encouraging. Further studies are needed to define their role in the management of asthma.

Abstract
A randomized trial of an instructional method was conducted in which school nurses taught children asthma self-management principles and skills, including peak flow monitoring, in 20-min, individual sessions over an 8-week period. Thirty-six children participated. An intervention group of 18 children received the teaching sessions. A control group of 18 children received regular care by the nurses, but no teaching sessions. The sample included 64% boys, 69% African-Americans, and 69% Medicaid recipients. The average age of subjects was 10.2 years. The two groups were demographically similar, but despite random assignment, the control group had a significantly earlier age of onset of asthma and tended to have had more asthma attacks in the preceding year. These factors were statistically controlled in outcome analyses. Results of group comparisons showed no significant differences in the number of postintervention emergency room visits and days absent from school. However, nurses reported that children who practiced breathing exercises had less anxiety during exacerbations, and the nurses' knowledge of the children's baseline peak expiratory flow rates facilitated care of the children. Nurses expressed the opinion that the individual sessions with students might be useful in motivating them to participate effectively in later group sessions. The intervention was well accepted by students, parents, and nurses. We believe that this intervention is promising as a practical, low-cost approach to enhancing children's asthma self-management skills and warrants further testing in a larger sample, with the intervention conducted over a longer period.

Abstract
During recent decades, asthma prevalence and mortality have increased rapidly worldwide among children, teenagers, and young adults. Little attention has been placed on the latter group. Therefore, we studied risk factors for intubation in young adults as potential severity markers predictive of death. We analyzed demographic data from a retrospective cohort of hospitalized asthmatic young adults, including all asthmatics aged 20-34 years admitted over a 10-year period (1984-1994) to the University of California, Davis, Medical Center, Sacramento, California. A total of 550 such asthma admissions were reviewed, involving 351 women and 199 men, mean age 27.9 +/- 4.2 years. Of this group, 180 young adults were white, 209 were black, 118 were Hispanic, 16 were Asian, and 27 were American Indian. By National Heart, Lung, and Blood Institute guidelines, there were 95 mild, 322 moderate, and 133 severe cases. Thirty-four young adults required intubation for their asthma. Significant risk factors identified for intubation were psychological factors and psychosocial problems odds ratio (OR) 25.0; 95% confidence interval (Cl) 12.4, 50.8, prior intubation (OR 23.6; 95% Cl 7.5, 42.8), language barrier (OR 17.3, 95% Cl 7.9, 38.0), prior asthma emergency room visit in past year (OR 10.2; 95% Cl 4.6, 16.0), crowding (OR 8.5; 95% Cl 4.6, 16.0), prior asthma hospitalization in past year (OR 8.3; 95% Cl 3.3, 20.8), family dysfunction (OR 7.2; 95% Cl 3.6, 14.3), active smoking/secondhand smoke exposure (OR 7.1; 95% Cl 5.1, 9.9), respiratory infection (OR 6.0; 95% Cl 3.2, 11.5), low formal education (OR 5.7; 95% Cl 2.9, 11.2), unemployment (OR 4.9; 95% Cl 2.5, 9.5), steroid dependence (OR 4.6; 95% Cl 3.2, 6.4), and atopy (OR 4.3; 95% Cl 2.1, 8.5). These variables are important determinants of baseline risk factors.

Abstract
Precise epidemiological data for the prevalence of childhood asthma were lacking for Switzerland until recently. In 1990 we performed a stratified cluster sampling of schoolchildren (aged 7, 12, and 15 years), using a parent completed questionnaire to obtain data for the 12 months prevalence of asthma symptoms and the lifetime prevalence of asthma diagnosis. A response rate of 97.5% enabled us to analyse 4,353 completed questionnaires. The prevalence of any asthma symptom during the last 12 months was 17.5% while only 4.8% of the children reported the diagnostic label "asthma". The 12 months prevalence of chronic night cough was 12% and is comparable to other European data. Wheeze (5.9%) was reported less often in Switzerland than in England. At the age of 7 years asthma symptoms such as wheeze, morning tightness, and allergen-induced symptoms were reported more often in boys than in girls; at the age of 12 and 15 the male preponderance was no more evident. For all asthma symptoms the male-female ratio decreased with increasing age of the children, while independently of age twice as many boys than girls reported the diagnostic label "asthma." We conclude that asthma symptom prevalence in Swiss schoolchildren is within the lower range of European data. Chronic night cough might be a more appropriate variable to compare prevalence rates between regions with different cultural and linguistic backgrounds that the symptom of wheeze. Evidence exists for a substantial underdiagnosis of bronchial asthma in Swiss children, especially in girls. Further evaluation is needed to define risk factors for underdiagnosis and the associated risk for undertreatment.

Abstract
There are significant concerns regarding the increased mortality of patients with asthma. Indeed the paradox of improved pharmacotherapy but worsening prognosis has been explored in depth in several studies including observations in epidemiology, access to medical care, and drug toxicity. Because of our ability to track all admissions to a tertiary-care hospital, we attempted to define the demographic data from a population of asthmatic children admitted for asthma in order to identify risk factors for intubation. We performed a retrospective cohort study of all asthma admissions excluding patients with cystic fibrosis. This study included all asthmatics aged 5-12 years admitted over a 10-year period (1984-1994) to the University of California at Davis Medical Center, Sacramento. A total of 300 such asthma admissions were reviewed, involving 135 girls and 165 boys, mean age 7.7 +/- 2.4 years. Of this group, 166 children were black, 70 were Caucasian, 49 were Hispanic, 14 were Asian, and 1 was an American Indian. By National Heart, Lung, and Blood Institute guidelines, this group included 147 mild, 117 moderate, and 36 severe cases. Thirteen children required intubation for their asthma. Significant risk factors identified for children requiring intubation, compared to those who did not require intubation, were secondhand smoke exposure [odds ratio (O.R.) 22.4; 95% confidence interval (C.I.) 7.4, 68.0], psychosocial problems (O.R. 13.5; 95% C.I. 5.1, 36.0), family dysfunction (O.R. 13.0; 95% C.I. 3.9, 43.9), upper respiratory infection (O.R. 10.2; 95% C.I. 3.4, 28.1), little formal education (O.R. 8.7; 95% C.I. 2.4, 31.6), prior asthma emergency room visit in past year (O.R. 7.2; 95% C.I. 1.9, 27.1), prior asthma hospitalization in past year (O.R. 7.1; 95% C.I. 2.2, 22.2), crowding (O.R. 6.9; 95% C.I. 2.5, 19.1), low socioeconomic status (O.R. 6.5; 95% C.I. 2.1, 20.8), steroid-dependent (O.R. 3.8; 95% C.I. 1.2, 12.1), parental history of allergy or asthma (O.R. 3.4; 95% C.I. 1.1, 10.0), and language barrier (O.R. 3.3; 95% C.I. 1.1, 10.6). Nonsignificant mild risk factors included inhaled cromolyn (O.R. 2.7; 95% C.I. 0.7, 10.0), atopy (O.R. 1.9; 95% C.I. 0.6, 5.9), and prior intubation (O.R. 1.6; 95% C.I. 0.2, 13.1). These risk parameters may be important determinants of baseline risk for asthma deaths and their recognition may have a significant impact on preventive measures.

Abstract
Mortality from asthma in Chicago is among the highest in the nation for 5-34-year-olds. Data for all hospitalizations among Chicago residents less than 35 years of age were examined to define characteristics that may be contributing to morbidity and mortality from asthma. From 1987 through 1989, the average annual age-adjusted hospitalization rate among persons less than 35 years of age in Chicago was 3.57 per 1000 persons. There were significant associations of community hospitalization rate with median income (r = -0.61, p < 0.001) and with proportion of community asthma hospitalizations using Medicaid, Medicare, or self-payment (r = 0.69, p < 0.001). Among 18-34-year-old men, asthma hospitalization rates for Medicaid recipients were 17.4-34.1-fold higher than among men using other forms of insurance. Asthma admissions using Medicaid, Medicare, or self-payment were more likely than those using other forms of insurance to present through the emergency department (79.3% and 66.4%, respectively, p < 0.001) and be discharged against medical advice (1.8% vs. 0.7%, respectively, p < 0.001). These data suggest that differential access to or utilization of health care may be contributing to asthma morbidity in Chicago.

Abstract
The asthma mortality rate has increased steadily over the past 15 years in the United States and has only recently shown signs of leveling off. It is widely believed, although unproven, that many asthma deaths may be preventable. We have addressed one critical factor in severe asthma by attempting a definition of risk factors for intubation using demographic data and a retrospective cohort study of hospitalized asthmatic teenagers. This study included all asthmatics aged 13-19 years admitted over a 10-year period (1984-1994) to the University of California Davis Medical Center, Sacramento, California. A total of 143 such asthma admissions were reviewed, involving 68 females and 75 males, mean age 16.4 +/- 2.3 years. Of this group, 85 teenagers were black, 34 were Caucasian, 14 were Hispanic, and 10 were Asian. By National Heart, Lung, and Blood Institute guidelines, there were 42 mild, 85 moderate, and 16 severe cases. Ten of the 143 teenagers studied required intubation for their asthma.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE To determine whether the number of emergency department (ED) visits for acute asthma exacerbations could be decreased by providing patients with a comprehensive program of asthma management delivered by a pharmacist and a physician. DESIGN Patients were selected from the ED and asked to attend a special asthma clinic that provided education about asthma and proper use of asthma medications, regular telephone contact between the pharmacist and patient, and an open-door clinic policy. SETTING A university-affiliated urban teaching hospital. PARTICIPANTS The study population consisted of 25 asthmatic patients who were at least 18 years of age and who were seen in the ED a minimum of 3 times in a 12-month period. MAIN OUTCOME MEASURES The number of visits to the ED for acute exacerbations of asthma was measured. Patients served as their own controls. The number of ED visits for asthma during the 6-month study period was compared with two 6-month periods prior to the study period for each patient. RESULTS The total number of ED visits for the 25 enrolled patients six months prior to their enrollment into the study was 92; the number of ED visits during the same months of the study in the prior year was 47. During the study period, there were only 6 ED visits for asthma exacerbations. CONCLUSIONS The comprehensive asthma management program reduced the number of ED visits for acute exacerbations of asthma.

Abstract
STUDY OBJECTIVE To evaluate whether providing a spacer device and a single, brief demonstration regarding its proper use would result in earlier resolution of asthma symptoms, improved school attendance, and decreased frequency of unscheduled medical visits for asthma among children receiving noncontinuous care in an urban emergency department (ED). DESIGN Randomized controlled trial. SETTING Urban hospital pediatric ED. PARTICIPANTS Eighty-four children with the chief complaint of asthma. INTERVENTION Children were enrolled in the ED at the time of an asthma attack and randomly assigned to one of two treatment groups. The spacer group received an inhaled beta-agonist at discharge from the ED with a spacer device. The control group received inhaled or oral beta-agonists without a spacer device. Both groups received other medications at the discretion of the evaluating physician who was not the interviewer in any case. A baseline questionnaire was completed and follow-up by telephone was done at 1 week, and 2, 4, and 6 months after enrollment. MEASUREMENTS AND RESULTS The spacer group reported significantly earlier resolution of wheezing (0 days vs 2 days, p < 0.01) at the 2- and 4-month follow-up assessments. They reported significantly fewer days of cough after an asthma attack at 2 months (1 day vs 3 days, p < 0.01) and 4 months (0 days vs 3 days, p < 0.01). The spacer group missed significantly fewer days of school following an asthma attack at 2 and 4 months (0 days vs 2 days, p = 0.05). There was no difference between the two groups on any outcome measures at the 1-week and 6-month follow-up assessments. CONCLUSIONS Introducing a spacer device to patients in a busy, inner-city pediatric ED is an effective and efficient intervention that improves the functioning of asthmatic children in terms of resolution of cough and wheeze and school absenteeism.

Abstract
The aim of this study was to determine the prevalence of asthma among United Arab Emirates school children aged 6-14 years. A cross-sectional study of 850 school children living in both urban and rural areas (average age 9.36 +/- 2.11 years, 46.8% boys and 53.2% girls) was conducted using self-administered questionnaires between October 1992 and May 1993. The population sample had a high prevalence rate of diagnosed asthma (13.6%), breathlessness or tightness in chest (9.7%), allergic rhinitis (22.9%), and nocturnal cough (8.9%). Allergic rhinitis was the most frequently seen respiratory illness when compared to other respiratory symptoms. The frequency of asthma, allergic rhinitis and eczema among parents reflected the same pattern as that seen in the children. Prevalence rate of asthma was not significantly higher in fathers (5.9%) than in mothers (5.3%). The differences between the sexes were not significant in any of the age group studied for any of the allergic conditions, except for diagnosed asthma in which the prevalence rate in males was significantly higher than that in females. On the whole, the prevalence rate of all the conditions increased with age. But the frequency of allergic rhinitis symptoms was significantly higher in mothers (16%) than in fathers (10.8%). These results are consistent with those obtained in neighbouring gulf countries and are higher than those of some developed countries, but the differences are not statistically significant.

Abstract
To determine whether death rates from asthma have been rising in South Africa, asthma mortality rates among coloured and white South Africans were calculated from official figures for the years 1962-1988. Sharp increases in the 1960s were noted in both groups. Since the early 1970s whites rates have generally shown a downward trend. In contrast, coloured rates have remained high, with a marked excess of male deaths. In the age stratum 5-34 years, there has been considerable fluctuation, with the long-term trend being slightly downward. Some increase in death rates occurred among the young in the early 1980s, but coloureds in this age group have shown falling rates in the most recent years. Coloured death rates in the younger age stratum have, however, continued to exceed whites rates, although by a decreasing margin, and have been high by international comparison. These group disparities are unlikely to be due to differences in certification or in coding. Variation in prevalence or severity of asthma may explain some of the disparity. However, these group differences, taken with well-known inequalities in medical care, suggest that preventable determinants of asthma deaths related to access to and quality of medical care may be important and accordingly a target for preventive strategies.

Abstract
The aim of the present study was to determine the prevalence of asthma-related symptoms in a group of primary school children, by means of a questionnaire completed by their parents, and their lung function using spirometry and the forced oscillation technique (FOT). Also investigated were diagnostic labeling and medical prescription. We approached 535 children, from two primary schools in Maastricht, the Netherlands. Completed questionnaires were received from 482 children (90%). Valid lung function values were obtained in 470 of these children (98%). The lifetime prevalence of wheeze and attacks of shortness of breath with wheeze was 29% and 19%, respectively. The period prevalence of wheeze was 15%, 13% reported chronic cough, and 10% attacks of shortness of breath with wheeze. The doctor-diagnosed asthma and bronchitis prevalence was 6% and 19%, respectively. Of the children diagnosed as having asthma, 69% used antiasthma medication; none of the children diagnosed as having bronchitis used antiasthma medication. A symptom-based asthma prevalence of 11% was calculated. Statistically significant differences in spirometric and FOT indices were found between the children with and without complaints. In conclusion, among the 482 investigated children a relatively high prevalence of unrecognized or misclassified, and therefore undertreated, asthma-related symptoms was found. These observations were confirmed by the lung function data, in that we found significant differences in spirometric and FOT indices between children with and without complaints.

Abstract
Asthma is a leading cause of morbidity in the United States and is a leading cause of disability in children. Prevalence has been shown to be highest in male children, blacks, and urban residents. Racial and residential differences have been attributed to economics. Medicaid claims data allow for the comparison of asthma morbidity and treatment of patients with different demography but of low socioeconomic status. Michigan Medicaid claims data for recipient children between 5 and 14 years of age were used to ascertain demographic factors associated with asthma treatment from 1980 through 1986. A cross-sectional analysis was used. Black asthmatics were found to receive medical care more frequently, but to obtain asthma drugs less frequently than other groups. The prevalence of different prescription asthma preparations also varied by race and residence. Black, urban residents obtained fixed-combination drugs more frequently and steroids less frequently than other groups. Rural patients, in general, had fewer medical contacts but obtained more prescription products per provider contact, whether black or white. Possible reasons for this variation are discussed.

Abstract
Air pollution is not spread evenly across demographic groups. Exposures and associated health risks appear to fall disproportionately on populations that are poor and nonwhite. Although scientific evidence documenting disparities in air pollution exposures, doses, and health effects is scant, the available data strongly support the contention that disadvantaged groups, many of whom are ethnic and racial minorities, routinely encounter levels of air pollution that are higher than average. The extent to which exposure differentials contribute to observed differences in health status by class and race is unknown, but worthy of further investigation. We recommend several steps, all of them feasible and most of them relatively inexpensive, to improve our understanding and ability to address environmental health disparities.

Abstract
This discussion of asthma management should be regarded as providing guidelines, not dogma. The underlying principles of asthma management include recognition of the variability of the disease and the importance of the underlying inflammatory condition. Clinical assessment is not enough and objective monitoring with PEFR or spirometry provides important data. The treatment protocols require individualization. It is important that the patient and family are team members working together with the medical staff toward a goal of good asthma management. In the discussion of the management of asthma, much emphasis was placed on spirometry and home measurement of PEFR. Office use of spirometry is now the norm for asthma management. Providing asthmatic patients with peak flow meters and instructions in their use is part of the routine care of asthma. Instruction of the patient and family in the proper use of medications is paramount. The MDI devices need to be prescribed with careful instructions regarding their use. When the patient comes in for follow-up, part of the examination should include the patient's demonstration of how he uses this device. Discussion of the proper and safe use of bronchodilators is important. Overuse of inhaled bronchodilators may be a reflection of increasing asthma or, at the very least, evidence that the patient does not understand appropriate treatment of asthma. If a patient is dependent on regular use of an inhaled beta agent, it is likely that he would benefit from therapy directed at the underlying inflammation of asthma. The patient and the family should understand the purpose of each medication, the side effects, and the risks and benefits of their use. In particular, if steroid medications are necessary, the reasons for their use should be explained. Carefully matching the severity of the asthma with the therapeutic protocols provides an organized approach to asthma treatment. Avoiding triggers of asthma and controlling the environmental exposure to potential triggers leads to lower medication requirements and less lability. Offering the family written instructions to cope with changes in the child's condition, based on assessment of clinical and PEFR observations, allows them more autonomy and comfort in the day-to-day care of the asthmatic child.

Abstract
BACKGROUND Despite advances in therapy, morbidity and mortality rates as a result of pediatric asthma appear to have increased during the past decade. Epidemiologic evidence suggests that these increases disproportionately affected black children and the urban poor. METHODS With use of data from the Medicaid Management Information System, we estimated the prevalence of asthma hospitalization in the 5- to 14-year-old Michigan Medicaid population for the period 1980 to 1986. RESULTS Large increases were seen between 1980 and 1984, with leveling off or a slight decline thereafter. In 5- to 9-year-old children, the prevalence of asthma hospitalization increased from 2.3 per 1000 persons in 1980 to 4.5 per 1000 in 1984. Ten- to 14-year-old children demonstrated an increase of 2.2 per 1000 in 1980 to 3.2 per 1000 in 1984. Comparable trends occurred in all strata defined by age, race, residency, and gender. However, the largest increases were noted in urban black children, in which the rate more than doubled from 3.2 per 1000 in 1980 to 7.1 per 1000 in 1984. The adjusted relative risk for asthma hospitalization associated with being male was 1.6 (95% CI: 1.5, 1.7), with being black was 2.2 (95% CI: 2.1, 2.4), and with living in an urban county was 1.1 (95% CI: 1.04, 1.4). CONCLUSIONS Within this relatively homogeneous low socioeconomic population, black race remained a strong predictor for asthma hospitalization, whereas urban residence was only minimally associated with this outcome.

Abstract
Asthma is one of the few diseases which has been reported to be common in the higher social classes. In order to assess the relationship between severe asthma and social class we analysed a national study of disabled adults undertaken by the Office of Population Censuses and Surveys (OPCS). The study estimated that there were 5.8 million people over 16 years with some degree of disability living in private households in England and Wales. Thirteen percent of disabilities were due to respiratory disease: 6% chronic bronchitis and emphysema, 3% asthma and allergy, and 4% other respiratory diseases. Among 10,000 individuals interviewed, 338 disabled adults reported asthma as a contributing cause of their disability. Of 291 cases with social class recorded, 41 (14%) were in social classes 1 and 2, 128 (44%) in social class 3, and 122 (42%) in social classes 4 and 5. An estimate of the relationship between social class and adult asthma in the general population was derived by calculating a morbidity ratio for the different social classes. The morbidity ratio for all social classes combined equals 100: for social classes 1 and 2 it was 63 (95% confidence intervals 48, 91); 93 (95% confidence intervals 77, 109) for social class 3; and 131 (95% confidence intervals 108, 153) for social classes 4 and 5. Adults in social classes 4 and 5 were approximately twice as likely to have severe asthma as those in social classes 1 and 2. This could be as a result of differences in the prevalence or treatment of asthma among the social classes.

Abstract
The percent rise in the number of asthma deaths was analyzed using data from the National Center of Health Statistics and compared for African-Americans and Caucasians. The rate of increase for African-Americans in the period 1979-1983 was nearly twice that of Caucasians, and the difference among genders for Caucasians was significantly higher for females. In Baltimore a high percentage (29%) of adult asthma patients (86.8% African-American) seen in an emergency room (ER) and living in the inner city had frequent visits (6 or more annually) to the ER. One-third of the patients used the ER exclusively for asthma management, and 39% delayed for at least 48 hr after onset of symptoms before seeking medical assistance. One-fourth had daily symptoms, and 11% of those regularly employed had missed 10 or more days annually because of asthma. Among the high ER users, 39% required more than one annual hospitalization for management of acute exacerbation of asthma symptoms. Risk factors for mortality and morbidity among inner-city and minority populations as well as potential areas of intervention are discussed.

Abstract
We examined trends in hospitalizations for asthma from 1967 to 1987 among members of a large health maintenance organization. During this time asthma discharges increased significantly among children, and especially among boys under the age of 5 years. Ninety-five percent of the increase in discharges among boys was explained by a corresponding increase in the number of boys who were hospitalized. Increased readmissions did not account for the rise. Changes in the International Classification of Diseases coding of asthma and diagnostic shift by physicians accounted for only part of the increase. A decline in hospitalizations since 1984 may reflect changes in the management of asthma in the emergency room and not a decline in severe asthma episodes.

Abstract
We evaluated various patient characteristics in patients hospitalized for asthma during 1987 to 1990. Potentially fatal asthma was identified in 26 of 87 adult patients (29.9 percent) hospitalized. Patients with PFA had increased frequency of prednisone use prior to hospitalization (p less than 0.001), shorter duration of symptoms before hospitalization (p less than 0.001), longer hospitalization (p less than 0.001), were more likely to have had three or more prior hospitalizations (p less than 0.001), and had reduced presenting peak expiratory flow rates (p less than 0.05). Major psychiatric diagnoses and noncompliance were significantly related to PFA cases. The diagnosis of PFA identifies a higher risk patient with asthma. The data suggest that at the time of hospitalization the PFA patient has had a shorter recognized prodrome of increased respiratory symptoms, reduced peak expiratory flow rates and greater likelihood of major psychiatric disease or noncompliance. Effective ambulatory control of PFA and non-PFA is advisable with earlier use and higher dosages of oral corticosteroids.

Abstract
Representative samples of 20-44 year old men living in 20 local authority districts in England were surveyed in 1986 by postal questionnaire and asked about symptoms associated with asthma and treatment for asthma. Regional health authorities provided information on all hospital discharges of men of the same age living in the same districts. Specific information was also provided on discharges where the primary cause of admission was for asthma. Admission rates for asthma were related to the prevalence of night time breathlessness and independently to the all cause admission rate for men of the same age. Admission rates were not significantly related to prescription rates of either corticosteroids or beta 2 agonists for symptomatic men. This lack of association is hard to interpret without further information on variation in the severity of disease. These data show that admission rates for asthma are not dictated solely by health service characteristics, such as availability of beds or the "style" of the physician, but also reflect need. More research is required on how best to reduce the local prevalence and severity of asthma.

Abstract
Duration of symptoms, medication use and follow-up medical care were examined over an 8-week period in children following emergency room treatment for an acute asthma episode. Two groups of children were compared: Short-course (N = 90) and Continuous Medication Users (N = 46). Over a third of Short-Course Users continued to report symptoms up to 6 weeks following the index episode with 31% reporting medication use at 8 weeks. Relapse, resulting in an emergency room visit, occurred in 26% of all study children. Factors associated with relapse included maternal smoking, female gender, prior hospitalization for asthma, cough, and medication use during the follow-up period.

Abstract
A 3 year-study of emergency room visits (total 50,300) to the paediatric clinic of the main teaching hospital in Kuwait revealed that the rates of bronchial asthmatic attacks increased significantly from 8.8% of all visits during the 1st year to 14.9% during the 3rd year. The seasonal distribution of asthmatic attacks showed maximum rates during the winter and minimum values in the summer, giving a very close inverse correlation to temperature and direct correlation to relative humidity. A similar, excellent correlation was seen between asthmatic attacks and upper respiratory infections. Occurrence of atmospheric pollen, which characteristically shows a bi-annual pattern i Kuwait, was not found to correlate with asthma attack rates. Neither was there any demonstrable effect of dust storms on the frequency of asthmatic attacks in the children. Independent of season, the boy to girl ratio among the asthma cases was remarkably constant, around 2:1.

Abstract
In a study of 2006 school children living in two urban areas of the Kingdom of Saudi Arabia, we used a questionnaire to collect details of age, sex, areas of residence, occupation, education, social class, parental history of asthma and information relating to parental smoking habit. The relative importance of these factors on the likelihood of children having bronchial asthma was assessed using a linear modelling analysis. The extent to which these factors affected the severity of bronchial asthma was also examined. A number of statistically significant associations between bronchial asthma and 'breathlessness' (P less than 0.0087), 'Father smoker' (P less than 0.0001), 'usually cough' (P less than 0.0001), 'pets' (P less than 0.0067) and 'Family history of allergy' (P less than 0.007), were found.
